Abstract: 1516251 Seaming non-metallic sheet material FKF BERLIN-FLEISCHWAREN UND KONSERVENFABRIK SCHULZ & BERNDT GmbH & CO KG 7 May 1976 [9 May 1975 26 Aug 1975] 18943/76 Heading B5K The plastics layers of two plastics/metal laminates are sealed together by applying heat to the laminates while pressing together the plastics surfaces to be welded, the pressure being built-up to sealing pressure during a time interval which is no more than 20%, preferably less than 10%, more preferably 3 to 5%, of the interval between the initiation of the build-up of sealing pressure and the beginning of the pressure drop off from sealing pressure at the end of the sealing period. Preferably, the laminates are in the form of lightweight metal foil container parts coated with polypropylene. Apparatus for sealing together the laminates comprises frame members la, 1b and sealing heads 2a, 2b carrying sealing dies 3a, 3b, respectively. A toggle mechanism 4 has one lever hinged to a compression linkage comprising a strut slidably guided in the member la and supporting the head 2b, and another lever hinged to a strut slidably guided in the member 1b and linked to the piston 5 of a closed pneumatic spring or buffer cylinder 6. The toggle mechanism 4 is driven by the piston rod of an hydraulic jack 7. To accommodate vertical relative motion between the parts la, 1b, 2a, 2b and the jack 7, either the jack 7 is pivotally mounted at its right-hand end or the jack 7 is fixed and the parts 1a, 1b, 2a, 2b are slidable vertically. At the start of a working cycle, the levers of the mechanism 4 are inclined at 45 degrees to their extended colinear position and the piston rod of the jack 7 moves to the left of Fig. 1 so that the die 3b rises towards the die 3a. At a preset angle, e.g. 15 degrees, before the extended position of the toggle levers the die 3b contacts the die 3a and sealing commences as a result of sudden build-up of pressure in the cylinder 6 which is already under a predetermined preimposed pressure. Sealing continues until the toggle levers have moved through their extended position to an inclination of, e.g., 15 degrees in the other direction. The cylinder 6 has returned to its original position and further extension of the jack 7 lowers the die 3b. The next sealing cycle is initiated by reversing the jack 7.
